最近的工作表明，内侧临时叶（MTL），包括海马（HPC）及其周围的边缘皮层，除了情节记忆的两个基本因素是对象（“什么”是“什么”（“是什么） ”）和位置（“ Where”）。简而言之，我们讨论了与空间相关的信息，其处理尚不清楚，大概是因为它的多个方面以及与对象相关的信息相比之下。现有文献，我们提出了“统一理论”，该理论解释了在每个统一理论中构建对象定位信号的大脑机制。腹侧路径在每个凝视位置的大规模背景图像。此视图中心信号反映了第一人称的观点，并通过空间不变的对象信号和视图中的相似性指定了环境中的同类中心位置。中心背景信号均来自相同的残留图像，沿着腹侧通路流进行了集成（即统一），尤其是在在特定位置代表特定对象的混凝土信号可能在HPC中发挥作用，这是整个场景的关键要素。
Recent work has shown that the medial temporal lobe (MTL), including the hippocampus (HPC) and its surrounding limbic cortices, plays a role in scene perception in addition to episodic memory. The two basic factors of scene perception are the object (“what”) and location (“where”). In this review, we first summarize the anatomical knowledge related to visual inputs to the MTL and physiological studies examining object-related information processed along the ventral pathway briefly. Thereafter, we discuss the space-related information, the processing of which was unclear, presumably because of its multiple aspects and a lack of appropriate task paradigm in contrast to object-related information. Based on recent electrophysiological studies using non-human primates and the existing literature, we proposed the “reunification theory,” which explains brain mechanisms which construct object-location signals at each gaze. In this reunification theory, the ventral pathway signals a large-scale background image of the retina at each gaze position. This view-center background signal reflects the first person’s perspective and specifies the allocentric location in the environment by similarity matching between images. The spatially invariant object signal and view-center background signal, both of which are derived from the same retinal image, are integrated again (i.e., reunification) along the ventral pathway-MTL stream, particularly in the perirhinal cortex. The conjunctive signal, which represents a particular object at a particular location, may play a role in scene perception in the HPC as a key constituent element of an entire scene.
